I’m really sorry you are being targeted by this ridiculous, mean girl stuff. Better you find out the true color of these people before you wasted more time. They are childish. A lot of these little friendship cliques that initially form don’t last. They are often based on convenience and proximity not shared values and common interests. So, it’s not to late to make friend - the good kind of friends. It will require you putting in effort and getting involved in clubs and activities that interest you. Do hat now and you’ll be ahead of the curve. The time to meet new, interesting people never ends.
